Trust me on this Ang...Mac accused some of Highjacking a thread yesterday...It is a given that it will happen.......and happen alot..
I would hope not. There is no such thing as a "Catholics only" or "Jews only" thread, for example. Anyone here can post anywhere they want. Generally, one should try to stay with what the posted article was discussing. Suppose you post an essay by Spurgeon, and are discussing the essay with some other freepers. Then, a group of people moves in and begin to talk about the mating habits of the red-necked wallaby. If it is done with the purpose of spamming the thread, then it might be a problem. There is nothing wrong, though, IMO, if the discussion evolves into something off the subject of the article.
If ya want cheese just ask. :)
